BRENNAN, OF DETROIT, MICHIGAN WINDOW STRUCTURE Application filed May 31,

My invention relates to window structures and has particular reference to that type wherein sliding sashes are used as distinguished from the type known ascasement windows.

An object of my invention is to eliminate the necessity of sash-weights for the purpose of retaining the upper and lower sashes in any position to which they may be adjusted.

By so doing I eliminate a large portion of the expense involved in the manufacture and assembly of such window structures.

Another object of'my invention is to so design the frame members of the sash units and the means for retaining them in position after adjustment that the complete assembly constitutes a fully weather stripped unit in itself and eliminates the necessity of providing independent units for the purpose .2 of weather stripping the structure.

Still a further object of my invention is to provide a yieldable assembly wherein the sash members may be rackedto some extent without distortion or breakageof any of the elements. This is an extremely advantageous feature inasmuchas all window structures are subjected to a greater or lesser extent, to pulls and twists of various sorts due to the incessant raising and lowering of the sashes and other manipulations thereof for divers and sundry purposes.

In accomplishing the above objects I have provided guide strips of flexible sheet metal which cooperate with grooves extending along the sides of the sash members, and still another meritorious feature involved in my invention is the particular shape of these guide strips. 1 have'so designed them that there are several points of direct contact with the sash grooves, each of which points may be easily and firmly adjusted to exert a greater pressure inwardlyon the sashes. In this way it is a very simple matter to adjust the structure to hold each of the sashes firmly in an adjusted position in case there should develop a tendency for them to slide downward along the guide strips after a long period of usage, a difficulty which not infrequently occurs with any sash type of window.

Yet a further object of my invention is to 1930. Serial No. 458,868.

provide sash frame members rolled from sheet metal into a shape which is designed to 00- operate in a most efiicient manner with the weather stripping, glass panes, and certain other novel features to be described hereafter, as well as constitute a light, easily manipulatable assembly.

Various other objects and meritorious features of my invention will appear from the following description taken in conjunction with the drawings wherein like numerals refer to like parts throughout the several figures and wherein:

Fig. 1 is a front elevation of my window structure assembly,

Fig. 2 is a section through the top frame member of the upper sash,

Fig. 3 is a section through the lower frame member of the upper sash and the upper frame member of the lower sash when the window is closed, I V

Fig. 4 is a section through the lower frame member of the lower sash, and

Fig. 5 is a section on line 55 of Fig. 3.

In Fig. l I have illustrated my assembled combination which comprises the frame structure consisting of the two side jamb members 10 and 12, and sill l4, and the head piece 16. Along the inner side of each of the j amb members l0 and 12 there is secured a pair of flexible metal guide strips one of each pair, 18 and 20, being illustrated in Fig. 1.

Each of the sash members consists of outer frame members 22, each of which is identical in structure and may be rolled from a sheet of metal into the shape illustrated. These outer frame members 22 are joined at their corners by welding or soldering as desired. The inner frame members 24 arealso all of identical structure and may be likewise rolled from a strip of metal into the illustrated desired shape. These frame members are secured as illustrated to the outer frame members in any desired manner, as by welding or soldering. A locking mechanism 26 is secured to the upper frame of the lower sash and cooperates with the vertical frame 24 of the upper sash to lock the sashes in any desired 7 relative position. The particular formation of the frame members 24 and the manner in which they cooperate with the locking mechanism 26, as well as the glass panes, constitutes an important part of my invention but will be made the subject matter of a separate application and described in detail therein.

The formation of each pair of flexible metal guide strips 18 and 20 is clearly illustrated in Fig. 5 of the drawings. Each of them consists of a substantially V-sha-ped strip, the arms of which are indicated by the numerals 28 and 30. While I do not intend to, specify any particular metal which must be used in this structure, I have found that bronze constitutes a very suitable material because of the high. degree of flexibility and springinc-ss which is inherent in that metal, particularly when formed into a strip of relatively small thickness.

The arm 28 of each strip is secured to the jamb 10 at spaced apart intervals along the len th thereof by nailing, or any other means which may be found. desirable. \Vhile I have not illustrated such structure, I contemplate securing a metal lining longitudinally along the length of each of the janibs and spot welding the arm 28 of each guide strip thereto atspaced apart points.

As is apparent from Fig. 5, two of these guide strips are secured along the length of each of the'window jambs 10 and 12 in parallel relation and the arm 30 of each is bent outwardly toward the sash frame member 22 and rolled at its outer extremity into a lip formation 32 which fits snugly into the groove 34 of rolled metal frame member 22 It will be noted that aside from the bend 36, whereby the bronze sheet is formed into a substantially Vshaped member, there is a second bend 38 intermediate the length of the arm 30 which is produced by a light scoring of the metal. Each pair of guide strips secured along the jamb on each side are spaced apart a distance which will permit the lip portion 32 to fall into the groove portions 34 of the upper and lower sash frames respectively.

While I have illustrated one form of seuring the resilient guide strips along the inner face of the window ja'mbs 10 and 12, I contemplate constructing the two bronze guide strips of each pair in a single piece and providing a flange which may be inserted into a saw-back groove provided along the inner face of the ambs. construction would facilitate the assembly of the structure and at the same time cut down the expense of manufacture on volume production. Such structure also would provide a more complete weather stripping.

It is therefore apparent that the upper and lower sash members are adapted to slide along these guide strips, the said guide strips functioning not only as a guide, but exerting inwardly toward the center of the sashes a yielding pressure to retain each of them in any position to which it may be raised or It is obvious that such a lowered. Should any weakening of the pressure exerted by guide strips develop it may be remedied in any one of three ways, each o which is extremely simple and requires but little time. A wedge shaped tool may be run along the bottom of the V to spread the V somewhat, a similar tool may be hastily run along within the lip .32 to 5 read the lip so that it will bear more force ully against the side walls of the groove 34, or a scoring tool may be run along the score 38 which will tend to spring the lip member further out toward the center of the sash.

I contemplate providing a strip of weather stripping material 39, such as felt, along the inner face of at least one of the guide strips in order to provide a more complete weather stripping. Such a strip may be secured along the inner face of the arm 30 of the inner strip by gluing or other suitable means prior to the assembling of the window structure.

While I have not, as already stated, describedmy frame members 22 or 24, with any amount of detail, it is obvious that they are so rolled as to provide the necessary grooves 34 along their outer edges and the tapered channel wall portions 40, which are adapted to cooperate with the glass pane 41 and putty 43 to form a more lasting, flexible joint than usual.

Secured along the underside of the head in an desired manner is a flange member 42wh 1ch constitutes a stop for the upper sash upon closin the same. This flange member has a depending portion 44 which drops from the head 16 and is provided with a rolled in portion 45. adapted to catch in the grooves 46 of the upper sash frame member 22. This will assist in retaining the upper sash in its closed position in the event that other means should fail and also provide an effective weather strip. Another weather strip piece 48 is secured by nailing, or any other suitable means to the sill 14 and is turned into a U- shaped projection 50 as indicated in Fig. 3 which is adapted to seat within the groove 34 of the lower frame member 22 of the lower sash, As in the case of the flange 42 this lower piece 48 constitutes an effective stop and weather stripping unit for the lower sash.

As is apparent, I have designed a window structure wherein sashes of inexpensive type ma be utilized without the assistance of sas weights to retain each of them in its adjusted position, the metal guide strips 18 and 20 on each side exerting a pressure inwardly upon each of the sashes to hold them in position. Furthermore, the pressure exerted upon the sashes to retain them in any desired position may be readily adjusted in any one of the several ways heretofore described without necessitating skilled. labor of any sort.

My entire assembly is made up of units which are easyto manufacture and assemble, thus reducing the cost of the completed article as well as providing an efficient window structure.

While I have illustrated a preferred embodiment of my assembly, it is to be understood that I intend to limit myself only within the scope of the appended claims.
